Summary

• Refactored stage0 to load OSTree logic from a dedicated ostree module by adding mod ostree; and importing the module entry points in main.rs, while preserving the existing call flow in PID1 handoff/mount setup. stage0/src/main.rsL4-L5 stage0/src/main.rsL381-L437
• Moved all OSTree-specific implementation (layout detection, cmdline normalization, stateroot path derivation, boot bind decision, and runtime mount setup) into stage0/src/ostree.rs. stage0/src/ostree.rsL1-L251
• Moved the OSTree unit tests into the new ostree module, as requested in review comments. stage0/src/ostree.rsL253-L290
• Committed changes on the current branch (02cf853) and created a follow-up PR record with title “Follow-up: move stage0 OSTree code into ostree module”.
